Abstract

Based on the view factor model,the irradiance distribution on the back of the bifacial photovoltaic module is investigated in this paper. According to the irradiance distribution calculation and the single diode electrical model of the equivalent circuit of the photovoltaic module,the power loss caused by micro-mismatch is simulated by using the I-V curve superposition method. A simple and accurate reflection spectrum model is proposed to calculate the reflection spectrum, and the effect of the reflection spectrum on the bifacial module output performance is quantified by the spectrum mismatch factor. Considering the factors affecting the power output of bifacial modules, simulations and experiments are carried out. The results show that the micro-mismatch loss caused by non-uniform irradiance distribution of module backside is generally less than 3.0%, while the mismatch losses in condition of grassland, concrete ground and snow are respectively It is 0.3%-0.5%, 0.5%-1.0%, 1.0%-3.0%. Due to the shading of the photovoltaic module mounting frame, the micro-mismatch loss increases by 0.5%-3.3%. The reflection spectrum is quite different in different module installation grounds. Through the modification of the reflection spectrum factor,the accuracy of the power prediction of the bifacial photovoltaic module can be increased from 76.3% to 92.3%.
